Walter is familiar to the Titans as he played the last seven years for the Houston Texans, often serving as the second wide receiver opposite Andre Johnson.

He had 65 catches and eight touchdowns for Houston in 2007, but his role had diminished with only 39 and 41 catches the last two seasons and five total touchdowns. He was a recent salary-cap casualty for a team that drafted a couple receivers last year and is expected to draft a more dynamic No. 2 receiver at the end of the month.

Spencer is the third veteran, interior offensive lineman the Titans have added. He joins Andy Levitre, who will start at left guard, and Rob Turner.

While Fernando Velasco is expected to remain the starter at center, right guard will be wide open and Turner and Spencer could compete with a draft pick or slug it out between them.

Seattle picked Spencer in the first round in 2005 out of Ole Miss and he played the last two years in Chicago, where offensive line struggles were a big issue.

“Both Kevin and Chris are established veterans in this league who have a great deal of starting experience,” said Titans general manager Ruston Webster said in a statement. “They have made significant contributions on good teams during their careers. We feel like they can come in and provide increased competition at their respective positions for us.”

The addition of Spencer could mean the end of overpriced Eugene Amano, who was hurt in the preseason last year and missed the entire 2012 season.
